SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 384,925, dated June 19,1888.

Application filed December 17, 1887. Serial No. 258,154.

To all whom, it may concern:

Be it known that I, HENRY MYERS, a subject of the Emperor of Germany,but now rcsiding at the city of Philadel phia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Spring Bed'Bottoms, of which improvements thefollowing is a specification.

My invent-ion relates to a bed'bottom having a metallic slatted bottomframe, on which are mounted upright helical or spiral springs inparallel rows at suitable distances apart, and with spiral wiresarranged diagonally in opposite directions and longitudinally betweenthe rows of upright springs, and so united therewith and with a wireborder as to produce an elastic bearing-surface, the principal object ofmy invention being to provide a more uniform surface in such type ofbed-bottoms and to more perfectly equalize the strain on the severalupright helical or spiral springs, thus rendering the same much moreserviceable, comfortable,

and durable, and, moreover, enabling the same to be readily handledwithout in the least affccting the shape or form thereof.

My invention consists in the peculiar arrangementand combination oftheseveral parts, to be hereinafter more fully described.

In the accompanying drawings I have illus' trated my invention in a formfound practically efficient, and in which Figure l is a plan view of myimproved spring bed'bottom, showing also the upper portion thereofpartly broken away; and Fi 2- is a longitudinal section of the same,showing also an end view of a series of rectangularshaped bed-slats forsupporting the bottom in position.

Referring to the drawings for a further description of my invention, Aisa metallic frame, made of iron, steel, or other suitable metal,and towhich is secured a series of longitudinal slats arranged parallel toeach other, and at right angles to these slats is arranged, parallel toeach other, a series of transverse slats, a, which are secured,respectively, to said longitudinal slats a and frame A. At the pointswhere the transverse and longitudinal slats cross each other at rightangles are mounted upright helical or spiral springs B, the spirals ofwhich enlarge in opposite directions from their centers, and thesesprings B are held in (No model.)

proper position verticallyin eyes 1), formed in either the longitudinalor transverse slats a or a, to receive their lower free extremities.

Single or double wires 0 and c, in spiral or other suitable form, arearranged in parallel diagonal courses running in opposite directionsfrom one side to the other of the bottom,

and these wires 0 and c are intertwined with,

the top spirals of the respective upright helical springs B, forming, asillustrated in Fig. l, a series of diamond-shaped figures. Runningparallel with the upright springs B, and between th emlongitudinall y,is aseries of coiled or spiral wires, (1 and d, which are intertwinedalso with the top spirals of said springs, and the wires 0' and 0',running diagonally'in opposite directions.

Around the outer extremities of the upper portion of the bottom isarranged aborder, E, composed of one or more coiled or spiral wiresintertwisted together, and to which the extremities or ends of thespiral or coiled wires 0 and 0, running diagonally in oppositedirections, as well as the parallel ones at and d, runninglongitudinally, are suitably attached, as clearly shown, for instance,in Fig. 1, by which arrangement a uniform bearing-surface and anequalized springing action of the bottom is insured with absolutecertainty and undue strain on the upright springs, which might at anytime be brought to bear upon the same, fully compensated for, and a verystrong, serviceable, cheap, and comfortable bottom obtained,

and such a one as may be easily handled without affecting its shape orform.

I am aware that a bed-bottom has been constructed with an upper andunder metallic frame withinterposed spiral or helical springs, as shownand described in the Letters Patent N 0. 203,023, of April 30, 1878. Iam also aware that a bed-bottom has been constructed solely of a seriesof spiral springs taperingin oppo site directions from their centerswith continuous coiled wires connecting the outer spirals of saidsprings in longitudinal and transverse directions on the upper and lowerfaces thereof, as shown and described in the Letters Patent N 0.303,393, of August 12, 1884. I am also aware that aspiralwire band hasbeen looped into the rings of the outer series of conical springs, forthe purposes of aiding and maintaining an upright position of thesprings and as serving to support the outer edges of the bed ormattress, as shown and described in the Letters Patent No. 263,888, ofSeptember 5, 1882, and therefore I do not claim, broadly, suchconstructions of spring bed-bottoms; but,

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

The combination of aspringbcd-bottom consisting of a slatted metalbottom frame, helical or spiral springs mounted on said frame at pointswhere the slats thereof cross each other, and the lower extremities ofsaid springs being held to place thereat in eyes formed in said slats,wires arranged in parallel courses and interlaced with each other andsaid springs, and with a border composed of coiled or spiral wiresintertwisted together, thereby forming a solid elastic web-like form oftop, in which all strain brought to bear thereon may be uniformlyequalized throughout, as shown and described.

In witness that I claim the foregoing as my invention I have hereuntoset my hand in the presence of two subscribing witnesses.
